Disclosed is a perpendicular magnetic recording medium comprising: (a) a
non-magnetic substrate including a surface with a stack of thin-film
layers formed thereon; and (b) a tilted perpendicular magnetic recording
layer on the surface of an outermost layer of said layer stack, wherein
the easy axis of magnetization of magnetic particles of said recording
layer is tilted in a radial direction at a preselected, controllable
angle up to about 45.degree. from vertical. Also disclosed are a method
and apparatus for forming perpendicular magnetic recording media with
controllably tilted perpendicular magnetic recording layers.
